I think eventually SSR would be an optional part of an upgraded reflections system (enabled by developer choice on a device range the developer specifies). For a good implementation SSR...

@scarletsky - you observations were correct - the fresnel implementation in PlayCanvas was not using the half-angle and this did result in non-standard specular lighting results that differed significantly from...

I wanted to follow-up on a this PR, with an idea that came up from discussions with @slimbuck + @mvaligursky - it became apparent that we could expose a way...

I should add that internally in the engine (once we have support) we would use the asynchronous shader compilation where possible - but with guarantees to developers that their projects...

It is probably related to having per vertex tangents - most models now use partial derivatives to calculate tangent space from interpolated vertex normals (smaller mesh data size) - I...

I investigated this and it seems vertex tangents are not coming through if the mesh is imported as fbx - so at runtime the `hasTangents` flag is not set so...
